All the Free Streaming Services That Just Might Be What You’re Looking For

https://ift.tt/33ttay1

Many of us right now are spending more time at home than we normally do, hunkering down as we shelter-in-place or limit the amount of time we traditionally spend outside of our homes. And there’s a good chance we may be turning to our various streaming services to keep ourselves occupied—Nielsen estimates that staying inside can lead to a nearly 60 percent increase in the amount of content consumers watch. But if you’re like me, you may have already exhausted the good stuff worth watching on your regular go-to services.

Before you pony up for yet another service to tear through, consider any of a number of free services at your disposal—and there are a lot. Some, like Disney+ and Apple TV+, offer a year for free to Verizon customers and new Apple devices users, respectively. Many popular platforms offer free trials that can range from anywhere between seven days to three months, including the soon-to-launch mobile-first service Quibi. Others are always free, and may be just what you need to switch up your options. Whatever your need, Gizmodo has compiled a lengthy but in no way exhaustive list of options to keep you busy.

Sling TV

For you live television die-hards, Sling TV is a service that offers live programming on the super-cheap, with a ton of customization and bundle options. Sling TV typically starts at around $30 per month, but the service this week introduced a free, ad-supported version of its service that includes free movies and TV as well as ABC News Live. It’s available on Chrome, Safari, Edge, and through apps on Roku, Amazon, or Android devices.

Kanopy

Kanopy is a sleeper hit for high-quality free films and documentaries, typically with a focus on independent filmmaking, foreign films, and classic cinema. Gizmodo named Kanopy the best free streaming service you can subscribe to, but the catch is that it’s not available everywhere (like New York City, unfortunately). The service is available through participating universities and libraries, so you’ll either need a school login or library card to sign up. Kanopy is available on iOS, Android, Android TV, Chromecast, Roku, Fire TV, and select smart TVs.

CuriosityStream

This streaming service is another Gizmodo favorite, and you may have access to it for free if you’re an Optimum or Suddenlink subscriber. CuriosityStream is a fantastic hub for documentaries and educational content as well as originals—so this is a service to consider if you’ve maxed out on garbage television and are looking for something a little more informative. If you’re not a customer of either of those ISPs, however, CuriosityStream is very, very affordable, starting at just $3 per month or $20 for the whole year. The service is available on the web, Fire TV, Roku, Chromecast, Android, Android TV, iOS, Apple TV, Xbox One, and select smart TVs.

Disney+

Verizon customers who are on unlimited data plans or Fios can still snag a 12-month subscription to Disney+, the digital vault for all of Disney’s catalog, plus National Geographic, Marvel, Pixar, and Star Wars. Disney+ is fairly cheap too, at $7 per month after a seven-day free trial. The service is available on Fire TV, Android TV, Apple TV, Chromecast, Roku, select smart TVs, Mac OS, PC, Chrome OS, Android, iOS, PS4, and Xbox One.

Apple TV+

Apple TV+ is another you have free access to if you’ve recently purchased a new Apple product. The service is $5 per month, but you can binge its originals for free during a seven-day free trial. Apple’s originals are pretty meh, but horror fans may enjoy Servant. Apple TV+ is available on the web, Apple devices, streaming platforms, and select smart- and AirPlay-enabled TVs.

IMDb TV

This often-overlooked streaming service available on web and Fire TV actually has a pretty decent roster of free movies and series. Don’t expect to see a ton of new releases, but you will get a nice mix of Hollywood blockbusters you’ve yet to watch.

YouTube

YouTube has plenty of free documentary content from channels like Vice or Frontline documentaries from PBS you can subscribe to and build out a nice portfolio of free content. But YouTube also offers free, ad-supported movies as well. Just head to the Movies & Shows tab and select “Free to watch.” Be forewarned: The selection here isn’t great, but you might find something of interest if you don’t mind combing through the garbage—and reader, there is a lot of it here.

Vudu

Vudu, a Walmart-owned service, actually has a pretty decent selection of content in its catalog of free, ad-supported movies section. As with other free services, you may have to dig a bit to find something of interest, but there’s a good mix of old and new here to choose from. Vudu is available on the web, Roku, Chromecast, Tivo, Playstation, Xbox One, Nvidia, iOS, Android, and select smart TVs.

Pluto TV

Pluto TV is a pretty good option for folks looking for a good selection of live programming for free, as this service has more than 250 channels to surf. There’s some on-demand content as well, which is great, but the service is ad-supported. Pluto TV is available on Fire TV, Android, Chromecast, iOS, Playstation, Roku, and select smart TVs.

Tubi

Tubi is a stellar ad-supported service with a ton of quality movies and series. Again, it’s ad-supported with breaks every 12 to 15 minutes—so this won’t be a service for someone who minds interruptions. But overall, it’s a great service if you’re just looking for something to put on, and a favorite of many of our Gizmodo readers. Tubi is available on Roku, Apple TV, Fire TV, Xbox, Chromecast, Tivo, Android, Xfinity X1, and Cox Contour.

Trials, trials, trials

Keep in mind that most major streaming services have trials that run anywhere from a week to several months. Quibi, which launches April 6, is currently offering a three-month free trial to users who pre-order the app. Streaming giants like Hulu, HBO, YouTube TV, and Netflix all offer free seven-day trials as well, if you’re not currently a subscriber (or mooching off a friend or family member’s account). CBS All Access is also a trial to consider, as it’s got great originals like Star Trek: Picard and Jordan Peele’s The Twilight Zone. And, if you’re an anime fan, don’t sleep on the 14-day free Crunchyroll trial—one of the longer trial periods for premium services that have been around awhile.

God To Ignore Quarantine And Continue Being Everywhere

https://ift.tt/2UeNL4M

HEAVEN—The CDC now recommends for everyone to stay home and avoid going out as much as possible. Despite this, reports are that God is breaking quarantine and going absolutely everywhere.

Hospitals, nursing homes, prisons — wherever He is needed, God is going. He is reportedly visiting everyone and checking on everyone in this time of need and not using any amount of social distancing. God is said to be following the absolute best practices, though, and is at no risk of making people sick but only making people better.

“We have absolutely no control over the guy,” said CDC spokesman Jim Wells, “which is extremely frustrating. We want to remind you, though, that you’re not God, so please stay put in small groups.”

God is also reportedly trying to get people to stop hoarding toilet paper and instead put their treasures in Heaven. Treasures that don’t include toilet paper.

Breaking: Paypal Now Available

Many of you told us you wouldn’t subscribe until we offered Paypal as a payment option. You apparently weren’t bluffing, so we finally caved and added Paypal. Now — like the unbeliever faced with God’s invisible qualities displayed in nature — you are without excuse.

How butterfly wings get blacker than black

https://ift.tt/3d1tEQh

Researchers have figured out the mystery behind ultra-black butterfly wings.

Some butterflies have ultra-black wings that rival the blackest materials made by humans, using wing scales that are only a fraction as thick.

Set against a piece of black construction paper, the wings of the male cattleheart butterfly look even blacker than black.

“Some animals have taken black to an extreme,” says Alex Davis, a graduate student in the lab of Duke University biologist Sönke Johnsen.

The butterflies they study are 10 to 100 times darker than charcoal, fresh asphalt, black velvet, and other everyday black objects. As little as 0.06% of the light that hits them is reflected back to the eye.

That approaches the blackest black coatings humans have made to help solar panels absorb more energy from the sun, or that line telescopes to reduce stray light.

Yet they achieve this light-trapping effect using wing scales that are only a few microns deep, just a fraction as thick as the blackest synthetic coatings.

In a study in Nature Communications, researchers report that ultra-black butterflies from disparate regions of the globe appear to have converged on the same trick.

The secret to making blacks this dark and lightweight, they say, isn’t a surplus of melanin—the pigment responsible for a crow’s feathers or a black cat’s fur. It’s an optical illusion created by the 3D structure of the butterflies’ wing scales.

Light goes into their scales, but very little of it bounces back out.

In the study, the researchers used high resolution scanning electron microscopy and computer simulations to examine the microscopic structures on the wings of 10 species of ultra-black butterflies and four regular black or dark brown butterflies from Central and South America and Asia.

Butterfly wings may look smooth to the naked eye. Up close it’s a different story. Magnified thousands of times, butterfly wings are covered in scales with a mesh-like surface of ridges and holes that channel light into the scale’s spongy interior. There, pillar-like beams of tissue scatter light until it is absorbed.

Until recently, the explanation for the incredible light-absorbing properties of some black butterflies was that it was due to a honeycomb-like pattern in the tiny holes on the scales’ surface.

But the new study suggests “that doesn’t matter,” Johnsen says. Looking at butterflies from four subfamilies—the widest range of ultra-black butterflies that have been examined to date—the team found that other ultra-black butterflies suck up similar amounts of light using holes with a variety of shapes and sizes, from honeycombs and rectangles to a chevron pattern.

It turns out the key differences between ultra-black and regular black scales lie elsewhere. When they looked at the butterflies’ wings under an electron microscope, they found that both ultra-black and regular black scales have parallel ridges on their surface and pillars within. But the ridges and pillars are deeper and thicker in ultra-black scales compared to “normal” black scales.

When the team mimicked different wing scales in computer simulations, scales lacking either the ridged surface or interior pillars reflected up to 16 times more light. That would be like going from ultra-black to dark brown, Davis says.

This 3D architecture is so good at swallowing light that the ultra-black scales still looked black even when coated with gold.

“You almost can’t make them shiny,” Davis says.

Similar deep blacks have popped up in other animals, such as peacock spiders and birds of paradise, which are known to reflect as little as 0.05% of visible light.

None of these natural beauties is quite as dark as the blackest synthetic blacks on record, which absorb more than 99.99% of incoming light using tightly packed “forests” of carbon nanotubes around 10 to 50 microns high. But what makes butterflies interesting, the researchers say, is they rival the best light-trapping nanotechnology, using structures that are only a fraction as thick.

Ultimately, the findings could help engineers design thinner ultra-black coatings that reduce stray light without weighing things down, for applications ranging from military camouflage—for stealth aircraft that can’t be seen at night or detected by radar—to lining space telescopes aimed at faint, distant stars.

Why ultra-black coloration has popped up again and again across the butterfly family tree is still unclear, Johnsen says.

The blackness on the wings of many male butterflies is darker than it is on their female counterparts, so one theory is it helps them show off to potential mates. The black regions always border white, colored, or iridescent patches, so the idea is they might work like a dark picture frame to make the brighter blotches pop.

“Artists have known for a long time that the same color can look very different on different backgrounds,” Johnsen says.

The next step, Davis says, is to figure out how many times butterflies have evolved ultra-black wings, and determine whether those species have anything in common that might help explain what favored the change.

“Why be so black?” Davis says. “We think it’s likely some sort of signal to mates or maybe a predator. But there’s a host of other possibilities, and we’re hoping to clear that up.”

Support for the research came from the Duke University biology department and a Sigma Xi Grant-in-Aid.

Ruger’s New PC Charger 9mm Brace-Ready Pistol

https://ift.tt/2ITFb6o

Ruger recently announced the newest version of its pistol caliber carbine is hitting distribution channels, and based on the success of the PC9, we’re reasonably confident it will find a ready audience. Like the 10/22 Charger, the latest addition to the lineup is a chopped-down version of an existing carbine, but is sold in a pistol configuration, rather than a factory SBR.

We’re currently in the process of wringing this one out, but for the moment the stats are as follows:

• 6.5-inch hammer forged barrel, threaded 1/2-28 for the muzzle device of your choice
• Polymer chassis system which accepts AR15 pistol grips
• Interchangeable mag wells to accept Glock and Ruger pistol mags
• Takedown barrel and fore end
• Pic rail section on rear of chassis to accept braces

The takedown feature means you can leave your can attached to the barrel, rather than unscrewing it

The takedown feature might seem to have limited use when teamed up with a six inch tube, but when used in conjunction with a can, it really comes into its own. You can leave the suppressor connected to the host and instead use the takedown feature as a QD mount – as an added benefit, the fore end doesn’t heat up anywhere near as much as the suppressor, so you can disassemble it without either waiting for it to cool, or using your shirt tail to avoid getting burned.

The pistol version of the PC carbine features a polymer chassis which accepts AR pistol grips

As part of our initial testing we added a Liberty Mystic X suppressor, Trijicon MRO, and SIG folding brace and it makes for a compact backpack gun- just the ticket for a run to the store to pick up more toilet paper …
